We’ve always annoyed our children by striking up conversations with tour guides and random students on all the tours we’ve done (middle schools, high schools and now colleges). That’s despite orders not ask questions of the tour guides in front of everyone because that’s embarrassing! It’s embarrassing to do it in front of people… they’ll never see again… To compromise, we recommend walking next to the guides and asking quietly. Afterwards, of course, the kids always want to know what was found out…
